Abstract:
Helisaeus Roeslin’s manuscript Speculum et harmonia mundi, Das ist Wellt Spiegel Erster Theil (1579) was conceived as part of a broader project comprising a Speculum ecclesiae as well as a Speculum naturae. This project was connected with a Chronology aiming to establish the precise date of the most important events in history as well as to advance some conjectures about the approaching eschatological future. This article presents some recent discoveries that shed new light on Roeslin’s chronological work after 1579, most importantly the incontrovertible attribution to Roeslin of the anonymous manuscript De potestatibus orbis Christiani, et politicis et ecclesiasticis, Discursus (1580). Here Roeslin presented his discovery of the numerical proportions governing the numbers of spiritual and temporal potestates in the three historical periods (Void, Law and Gospel), affirming that these numbers were now nearly fullfilled, along with their ensuing eschatological implications. We show how Roeslin published this discovery in his Kurtz Bedencken (1583) against the calendar reform and again in 1612 in a short tract on the occasion of the coronation of Emperor Matthias I. The article focuses in particular on the appended broadsheet Tabella des Welt Spiegels, which displayed the completion and culmination of history, according to the astronomical revolutions of the planets as well as the numbers of temporal and spiritual governors.

Abstract:
A finite element approach is used to calculate the components of forces and moments acting on a square solar sail at a sun-sail distance equal to one astronomical unit. The model takes into account the deformation effect induced by the solar radiation pressure, where the incidence of the reflected photons changes as a function of the local orientation of the sail surface. Assuming a specular reflection model, the analysis shows that the maximum value of the transversal thrust component takes place when the solar zenith angle is about 36°, which is in accordance with the result available for a classical flat solar sail. Notably, the modulus of the moment due to the solar radiation pressure takes its maximum value approximately at the same (solar zenith) angle.

Abstract:
The effect of satellite mega-constellations on astronomical observations in the visible, near-infrared, and thermal infrared domains is estimated using a simple methodology, which is applied to ESO telescopes and instruments as examples (radio and (sub-)millimetre domains are not considered here). The study considers a total of 18 constellations in development by SpaceX, Amazon, OneWeb, and others, with over 26 thousand satellites, constituting a representative distribution. This study uses a series of simplifications and assumptions in order to obtain conservative, order-of-magnitude estimates of the effects: the satellites are assumed to be uniformly spread over the Earth’s globe, and their magnitude is estimated using a simplistic model calibrated on actual observations. The effect on various types of ground-based telescopic observations is estimated using a geometric probabilistic approach. The “trains” of very-low altitude satellites typically observed immediately after launch are extremely bright due to their very low orbit. They also fall very quickly in the shadow of the Earth after sunset. However, this initial bright state is not considered further, as the satellites quickly disperse into their higher altitude orbits. The number of illuminated satellites from the constellations above the horizon of an observatory ranges from approximately 1600 immediately after sunset, decreasing to 1100 at the end of astronomical twilight, most of them (∼85%) close to the horizon (below 30° of elevation). The large majority of these satellites will be too faint to be seen with the naked eye: at astronomical twilight, 260 would be brighter than magnitude 6 (i.e. visible in exceptional conditions), 110 brighter than 5 (i.e. visible in good conditions). Again, most of them (∼95%) will be close to the horizon (below 30° of elevation). The number of naked-eye satellites plummets as the Sun reaches 30−40° of elevation below the horizon. Specular flares and occultations by satellites are expected to cause only negligible effects on telescopic astronomical observations. The light trail caused by the satellite would ruin a small fraction (below the 1% level) of telescopic exposures using narrow to normal field imaging or spectroscopic techniques in the visible and near-infrared during the first and last hours of the night. Similarly, the thermal emission of the satellite would affect only a negligible fraction of the observations in the thermal infrared domain. However, wide-field exposures and long medium-field exposures would be affected at the 3% level during the first and last hours of the night. Furthermore, ultra-wide imaging exposures on a very large telescope (where saturation of the satellite trails has a ruinous effect on the detectors, such as those from the National Science Foundation’s Vera C. Rubin Observatory, formerly known as LSST), would be significantly affected, with 30–40% of such exposures being compromised during the first and last hours of the night. Coordination and collaboration between the astronomical community, satellite companies, and government agencies are therefore critical to minimise and mitigate the effect on astronomical observations, in particular on survey telescopes.

Abstract:
Concentrating solar collectors direct the sunlight towards a focus point or focus line. Relevant parameters are the fidelity of the concentrator with respect to its ideal parabolic shape, its stiffness under wind and gravitational loads, the angular accuracy of the tracking and the solar weighted specular reflectance of the reflector. Additional aspects refer to the long term durability and ease of cleaning of the reflector surface. Solar concentrators require lower geometrical precision than astronomic apparatus. Therefore, more cost effective designs are possible by using up the overall acceptable error budget to a level that collection efficiency of the reflected sun rays is still very efficient. Understanding the impact of the different parameters describing the quality of the concentrator with respect to system performance and cost is necessary for an advanced and efficient concentrator design. DLR has recently developed guidelines to measure the most relevant concentrator characteristics in its qualification center QUARZ. This paper presents the relevant parameters of mirrors for concentrating solar collectors and discusses their economic impact.

Abstract:
“God’s Deaf and Dumb Instruments: Albert the Great’s Speculum Astronomiae and Four Centuries of Readers” is a study of the reception and influence of what is perhaps the most important work dealing with astrology to be produced in the Latin West during the middle ages. In order to determine the impact and importance of the Speculum I have dealt with questions relating to its authorship and dating, while studying its contents in the context of Albert’s larger body of work as well as the readers who found it useful and how they approached the Speculum. I have studied these readers both directly, through a study of thirty-five of the fifty-nine surviving manuscripts, as well as indirectly through a consideration of the way that other writers used the Speculum through the end of the fifteenth century. In the course of my research I travelled to archives in England, Italy, Switzerland, Germany, and the United States to study codices containing the Speculum, as well as examining microfilm copies of volumes housed in the Ambrosiana collection of Notre Dame University and in the Pope Pius XII Vatican Film Library at St. Louis University. My focus was upon the works that came to be bound with the Speculum and the marginalia readers left behind, as well as the accuracy of individual copies of the text. Furthermore, I have studied the writings of an array of authors, from the thirteenthcentury physician Peter d’Abano, to the fifteenth-century humanist Pico della Mirandola, to determine how these scholars viewed astrology and the place of the Speculum in their writings. In this way I have been able to demonstrate that astrology was central to the medieval worldview of intellectual elites. The Speculum astronomiae, which I demonstrate was indeed written by Albert the Great around the year 1260, served as an important component of the preservation of the study and practice of astrology as a discipline permissible to Christians. Standing as a semi-canonical defense of the science, physicians, astrologers, natural philosophers, and those interested in doctrinal purity read it with profit, while both defenders and detractors of astrology found it important to address the Speculum in their own work.
